For almost 80 years, the Old Kosciuszko Bridge connected Brooklyn and Queens in New York. Much like many other bridges its age, it is being replaced due to capacity issues and deterioration. When it was completed in 1939, it was built for 10,000 cars per day. Unfortunately for the people who needed to use that bridge that past few decades, around 180,000 cars used it.
In the beginning of October, the old bridge, which sits next to the partially completed new bridge, was officially imploded, amid fanfare. Twenty-two million pounds of steel, spread across 20 spans (10 on the Brooklyn side, 10 on the Queens side) fell to the earth below after the explosions were triggered by a computer.
All of the steel that was imploded was located above ground, but there were some environmental concerns about the span that was above the Newtown Creek. To avoid this, the center part of the bridge was dismantled and slowly lowered to a barge below. A video of that process can be watched below the video of the implosion.
Now that the old bridge is out of the way, the new Kosciuszko Bridge is expected to be fully complete in the year 2020. The total project contract amount is $554.77 million.

Demolitions by implosion seems like the easiest way to knock down a structure, but there is so much preparation that goes into it that even the slightest mistake can have a huge impact. When smokestacks are demolished correctly, it can be a thing of beauty, like when these two silos in Scotland hit each other midair or when this asbestos filled stack was precisely demolished to fall into a pool of water. Things didn’t go so smoothly for demolition crews in Denmark last week, however.
